Figured I'd start a log, I've been patiently finding good deals on 6400aaks drives for a raid 0 project. My initial plan is to have 2 in raid 0, and one just connected for backup. Currently my 6400aaks is a game/program drive with 2 older wd400 40gb drives in raid 0. These wd400's were great as my first raid 0 project, but they barely keep up with the single 6400aaks. I will be using my onboard ich10r controller. Here are single drive results (screens coming soon) WD6400AAKS-007AB0 (Caviar SE16 purchased 5/2008) HDTach - HDTune - WD6400AAKS-75A7B0 (Caviar SE16 purchased 3/2009) HDTach - HDTune - WD6400AAKS-22A7B0 (Caviar Blue purchased 2/2009) HDTach - HDTune - WD400 40GB x2 In Raid 0 Results ( ) - HDTach - HDTune - The WD400's have proven reliable, quiet and cool running, definately great drives. I don't know what I'll do with them now...just storage for now, maybe load them into a family member's PC or something. Now from what I've learned the 75a7b0 and 22a7b0 are oem drives while the 00a7b0 is a retail drive part. As I continue this log feel free to give me suggestions and opinions. The reason I'm not planning to do all 3 drives in raid is purely because I'm not completely confident in maintaining all my data on a raid array this being my 2nd raid setup. That and I have all my info already backed up on my original 6400aaks atm...I'd have to copy it to a very slow seagate 500gb 7200.9 if I went with 3 drive raid...it'd take forever! Having a drive not in raid for backup use will provide me a sense of security in that respect. Thanks for looking!
